It provides a reliable and cost-effective solution for short-range connections within racks or between adjacent racks, supporting high-bandwidth data transfer without the need for additional transceivers or fiber optics. With a low signal delay of approximately 4.5 nanoseconds per meter and an impedance of 110 ohms, it ensures stable performance in demanding data center environments.\u003c\/p\u003e \u003ch6\u003eKey features\u003c\/h6\u003e \u003cul\u003e \u003cli\u003eDirect attach copper cable that delivers 25 Gbps connectivity for fast data transfer.\u003c\/li\u003e \u003cli\u003eThree meter length ideal for linking servers, switches, or storage devices within or between racks.\u003c\/li\u003e \u003cli\u003eCompatible with a range of HPE equipment including SN2410 switches, Primera storage arrays, and StoreOnce backup systems.\u003c\/li\u003e \u003cli\u003eMaintains signal integrity with 110 ohm impedance, reducing errors and improving reliability.\u003c\/li\u003e \u003cli\u003eLow latency with signal delay around 4.5 nanoseconds per meter, supporting latency-sensitive applications.\u003c\/li\u003e \u003cli\u003eCompact 4.5 mm diameter and 23 mm bend radius allow easy routing through cable management systems and tight spaces.\u003c\/li\u003e \u003cli\u003eEliminates the need for transceivers, lowering both cost and power consumption.\u003c\/li\u003e \u003cli\u003eOperates reliably within typical data center temperature ranges from 32 °F to 158 °F.\u003c\/li\u003e \u003c\/ul\u003e \u003ch6\u003eKey specs\u003c\/h6\u003e \u003cul\u003e \u003cli\u003eData rate: 25 Gbps\u003c\/li\u003e \u003cli\u003eCable length: 3 meters (approximately 10 feet)\u003c\/li\u003e \u003cli\u003eImpedance: 110 ohms\u003c\/li\u003e \u003cli\u003eSignal delay: ~4.5 nanoseconds per meter\u003c\/li\u003e \u003cli\u003eCable diameter: 4.5 mm\u003c\/li\u003e \u003cli\u003eBend radius: 23 mm (single bend)\u003c\/li\u003e \u003cli\u003eOperating temperature: 32 °F to 158 °F\u003c\/li\u003e \u003cli\u003eConnector type: SFP28 to SFP28\u003c\/li\u003e \u003c\/ul\u003e \u003ch6\u003eConnectivity and compatibility\u003c\/h6\u003e \u003cp\u003eThis cable is designed to plug directly into any HPE device equipped with SFP28 cages, making it a seamless choice for expanding or upgrading existing 25 Gigabit networks. It works well with HPE SN2410 top of rack switches, Primera storage arrays, and StoreOnce backup systems, ensuring broad compatibility within HPE data center environments. The direct attach design simplifies installation by removing the need for separate transceivers.\u003c\/p\u003e \u003ch6\u003eInstallation and setup\u003c\/h6\u003e \u003cp\u003eInstallation is straightforward thanks to the cable’s flexible design and manageable length. The 4.5 mm diameter and 23 mm bend radius allow it to be routed cleanly through cable trays and around corners without risking damage. Its 3-meter length is well suited for connecting devices within the same rack or between adjacent racks, making it a practical choice for data center layouts that require short, high-speed links.\u003c\/p\u003e \u003ch6\u003eIdeal uses and environments\u003c\/h6\u003e \u003cp\u003eThis cable fits well in data centers that require efficient 25 Gigabit connections for servers, switches, and storage systems. It supports environments where low latency and stable signal integrity are critical, such as virtualization clusters, high-performance computing, and real-time analytics. Its temperature rating aligns with typical hot and cold aisle conditions, making it reliable for standard data center deployments. It is a strong option for IT teams looking to upgrade from 10 Gigabit links to higher bandwidth without increasing power consumption or complexity.\u003c\/p\u003e","brand":"HPE","offers":[{"title":"Default Title","offer_id":51038203478335,"sku":"KEE-0SQ4-C75","price":212.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0888\/0609\/7215\/files\/0855237_kee-0sq4-c75.webp?v=1750266896","url":"https:\/\/www.beingshipped.com\/products\/kee-0sq4-c75","provider":"Being Shipped","version":"1.0","type":"link"}
